Question

A room has an area of 456 square feet. One dimension is 5 feet more than the other. Find the dimensions of the room.

Answer 1

Draw a rectangle. Label the length x and the width (x+5).
A = L*W => x(x+5)=456 => x^2 +5x-456=0 => Solve for x using Quad formula.
x=19 and x=-24

Answer 2

So your dimensions are 19 and 24
